The ADL5335 is a digital gain amplifier (DGA) optimized for use in wireless transmitters. A differential input and single- ended output facilitates a balun free connection between the broadband integrated transceivers with differential outputs and the RF gain blocks and drivers amplifiers with single-ended inputs.
The gain is programmable via a standard Analog Devices, Inc., serial peripheral interface (SPI) port from a maximum gain of 12.0 dB down to a minimum gain of −8.0 dB with a gain step size of 0.5 dB. The ADL5335 also features a fast attack function where the gain can rapidly increase or decrease by the application of a single pulse.
The use of a thermometer-based digital step attenuator (DSA) ensures that gain changes are fundamentally glitch free. The ADL5335 is packaged in a 4 mm × 4 mm, 16-lead LFCSP. A fully populated evaluation board and system demonstration platform (SDP)-based control software are available.

Evaluation Kits (1)
The ADL5335 is a DGA that has a differential input impedance of 50 Ω and a single-ended output impedance of 50 Ω. User Guide UG-1206 describes how to use the EV-ADL5335SD1Z to verify the operation of the ADL5335.
The EV-ADL5335SD1Z is a fully populated, 4-layer, FR4-based evaluation board that is designed to allow the user to easily evaluate the features and performance of the ADL5335.
Complete specifications for the ADL5335 are available in the ADL5335 data sheet from Analog Devices, Inc., and should be consulted in conjunction with User Guide UG-1206 when using the evaluation board.
Tools & Simulations
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
